How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of wireless headphones that double as a fun, glowing accessory and can still plug in when a plane seat only offers a jack, choose SIMGAL RGB Cat Ear; if you need to turn your own wired headphones into a wireless setup for flights and car audio, choose ALYNIC AUX. These two are not really rivals — one is a headset, the other is the adapter that makes any headset work over Bluetooth. Buying the right one comes down to what you already own and how you actually fly.
• SIMGAL RGB Cat Ear — biggest strength: a complete on-ear headphone with 50mm dynamic drivers, RGB cat ears, memory foam pads, a built-in mic and dual Bluetooth 5.0 / 3.5mm connectivity, so it works wirelessly or wired.
• SIMGAL RGB Cat Ear — biggest trade-off: the RGB lighting and the microphone only function in Bluetooth mode, and the lights and mic go dead once you switch to the 3.5mm cable.
• ALYNIC AUX — biggest strength: a tiny 2-in-1 Bluetooth transmitter and receiver that adds wireless audio to non-Bluetooth sources like plane seatback screens, older TVs and car stereos, with an aircraft connector included.
• ALYNIC AUX — biggest trade-off: it makes no sound on its own — it is an accessory, so you still need your own wired headphones or speakers to use it.
• Who each pick is for: SIMGAL RGB Cat Ear for someone who wants one ready-to-go headphone for music, gaming and study; ALYNIC AUX for a traveler who already loves their wired headphones and wants to cut the cord on a plane, in a car or at home.
The SIMGAL RGB Cat Ear (model B90) is a full headphone, not an accessory. It runs Bluetooth 5.0 with roughly 10 meters of range, so you can leave your phone on a seat or desk and move around. The 50mm dynamic drivers cover a 20 Hz – 20 kHz frequency range, which is the standard full-range span you want for music, videos and games. The cat ears and the ear-shell logos light up in RGB, and there is a button on the ear cup to switch the lighting off when you would rather not glow.
Here is the part that matters most for travel. The headset ships with a 3.5mm audio cable, so if your plane seat has a wired jack and no Bluetooth, you can plug in and keep listening. That is a genuinely useful fallback. Just understand the trade-off: in wired mode the RGB lights and the microphone stop working, so you are getting plain audio only. In my opinion, this is the right pick for a student, a younger gamer, or anyone who wants one headphone that handles music, calls and a bit of personality. Skip it if you want a subtle-looking headset, or if you mainly fly and need something that adds Bluetooth to an existing pair of headphones you already trust.
ALYNIC AUX: Who It's For
The ALYNIC AUX is a completely different animal. It is a pocket-sized Bluetooth 5.0 adapter that works two ways. In TX (transmit) mode it takes audio from a non-Bluetooth source — a TV, a game console, a plane's entertainment system — through the 3.5mm AUX port and sends it wirelessly to your Bluetooth headphones or speaker. In RX (receive) mode it does the opposite: it receives Bluetooth from your phone or computer and feeds audio into a car stereo, speaker or older sound system through the AUX jack.
The kit is built specifically for travel and driving. You get the transmitter/receiver itself, an aircraft audio connector for plane seat jacks, a USB-A to USB-C charging cable, a 3.5mm to AUX audio cable, a 3.5mm metal audio adapter and a manual. It supports a 10-meter range, keeps a stable connection for roughly 6–8 hours per charge, and the manufacturer states it resists interference from obstacles like doors, walls and Wi-Fi routers. Supported codecs include SBC, AAC, MP3 and WAV, and audio output is stereo.
Side-by-Side: Which Should You Choose?
• Best for a complete, ready-to-use headphone → SIMGAL RGB Cat Ear. It plays audio out of the box with no extra gear.
• Best for turning your existing wired headphones wireless → ALYNIC AUX. TX mode converts a plane's seatback jack into a Bluetooth signal for your own headphones.
• Best for flights with a wired seat jack → it depends on what you own. Have no headphones? Go SIMGAL and use its 3.5mm cable. Already have headphones? Go ALYNIC AUX.
• Best for car audio → ALYNIC AUX. RX mode plus the built-in mic and hands-free call buttons are made for driving.
• Best for music, gaming and online classes → SIMGAL RGB Cat Ear. The 50mm drivers, memory foam pads and adjustable folding headband suit long sessions.
• Best for hands-free calling on a headset → SIMGAL RGB Cat Ear. Its noise-reducing mic handles calls, as long as you stay in Bluetooth mode.
• Best for a compact travel accessory → ALYNIC AUX. It is small, plug-and-play and comes with an aircraft connector and both cables.
• Best for someone who wants visual flair → SIMGAL RGB Cat Ear. The RGB cat ears and ear-shell logos are the whole point, and you can switch them off.
If I had to pick one, I would buy the SIMGAL RGB Cat Ear. It is a finished product: you charge it, pair it, and you have music, calls and a wired backup for plane jacks, all in one item with memory foam pads and 50mm drivers. The ALYNIC AUX is excellent at what it does, but it only makes sense if you already own wired headphones you are happy with and specifically want to free them from cables. Buy the adapter for the job it solves; buy the headphone if you just want to listen.
are bluetooth headphones allowed on flights
Yes. Airlines allow Bluetooth headphones in the cabin; the restriction is on transmitting during specific phases like takeoff and landing, when crew may ask you to switch devices off or to airplane mode. Once in the air, Bluetooth headphones are commonly used. The SIMGAL RGB Cat Ear pairs over Bluetooth 5.0, and the ALYNIC AUX lets you use your own Bluetooth headphones with a plane's wired system.
do bluetooth headphones work on flights
They work, but only if the seat's entertainment system supports Bluetooth — many still use a wired 3.5mm jack. That is where the ALYNIC AUX earns its place: its TX mode takes audio from a non-Bluetooth source and sends it wirelessly to your headphones. The SIMGAL RGB Cat Ear sidesteps the issue entirely, since it ships with a 3.5mm cable for wired listening.
do delta flights have bluetooth for headphones
Bluetooth availability depends on the aircraft and the entertainment system installed, and it varies by plane rather than by airline rule. The safe assumption is that you may get a wired 3.5mm jack instead. Carrying a 3.5mm cable for the SIMGAL headset, or the ALYNIC AUX with its aircraft connector, covers both cases.
are bluetooth headphones ok on flights
They are fine for listening, and both products here are built with travel in mind. The ALYNIC AUX even includes an aircraft audio connector and both a 3.5mm to AUX cable and a metal audio adapter for plane and car jacks.
